setLocationMode in Device Type possible?

Even at that, I am so new that I don’t even know how to get the SmartApp to react to the event. I’ve looked at the Input statement in Preferences to set that to the SimpliSafe device. Then I put a Subscribe in the install function (according to docs). I used the sendevent from this chain, but it doesn’t activat the SmartApp. I’m very new.

Here is the device type.
